Methods and compositions for producing copper accumulating plants to slow decomposition and enhance carbon storage

Abstract

The present disclosure relates to plant cells, plants, and plant parts comprising a promoter sequence operably linked to a Copper Transporter 1 protein and / or a Nicotianamine Synthase 1 protein. The plant cells, plants, and plant parts optionally further comprise one or more additional heterologous polynucleotides encoding additional promoter sequences operably linked to additional polynucleotide sequences encoding any one or more of an Antioxidant Protein 1 (ATX1) protein, a Heavy Metal ATPase 4 protein, a Heavy Metal ATPase 5 protein, a Heavy Metal ATPase 9 protein, and / or a Yellow Stripe Like 16 protein. The present disclosure also relates to methods for increasing copper resistance and / or accumulation in a plant cell to reduce fungal decomposition in a plant cell, plant, or plant part and to enhance carbon storage.
